How do I find the values of x & y without using the Pythagorean theorem?

It’s okay if you use it to give me the answer however, I don’t understand how you wouldn’t use it.

Answer 1

9514 1404 393

Answer:

23) x=20; y=10√3

24) x=4√2; y=8

25) x=12; y=3+6√3

Step-by-step explanation:

Recognize that all of the triangles involved here are one of the two "special" triangles. By previous use of the Pythagorean theorem, or your familiarity with the trig functions of the "special" angles 30°, 45°, 60°, you know the following side ratios:

45°-45°-90° triangle: 1 : 1 : √2

30°-60°-90° triangle: 1 : √3 : 2

Using these ratios, you can solve these figures "by inspection."

23) x = 2((10√2)/√2) = 20

y = √3((10√2)/√2) = 10√3

24) x = 4√2

y = (4√2)√2 = 8

25) x = 6·2 = 12

y = 3 +6√3 . . . . . 3 units more than the longer leg of the 6 : 6√3 : 12 triangle

The can shown has a diameter of 3 inches and a height of 5 inches. Find the lateral surface area of the can.

Answers

Answer:

Lateral surface area of can = 47 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of given can = 3 inches

Height of given can = 5 inches

Find:

Lateral surface area of can

Computation:

Radius of can = 3 / 2 = 1.5 inch

Lateral surface area of can = Lateral surface area of cylinder

Lateral surface area of cylinder = 2πrh

Lateral surface area of can = 2πrh

Lateral surface area of can = 2(3.14)(1.5)(5)

Lateral surface area of can = 47.1

Lateral surface area of can = 47 inch² (Approx.)

find the area of the square

Answers

Answer:

100 sq units

Step-by-step explanation:

hypotenuse of the right triangle is the length of the square and we can find it by using the Pythagorean Theorem:

6² + 8² = c²

c² = 36+64

c² = 100

c = √100

c = 10

Answer:

1) 2400 sq feet

2) $93.75

3) A (first answer)

Step-by-step explanation:

1) replace the 6 inches with 60 feet and 4 inches with 40 feet. We do this bc 1 inch = 10 feet. Then multiply 60 x 40 to get 2400 sq feet

2) we know that 25% off of 100 is 75. Then to add 25% back to 75 we find 25% of 75. 25% of 75 is 18.75. So we add 18.75 + 75 to get $93.75

The angle m∠CBE between the intersection of the chord and tangent line is equal to 41°

How to calculate for angle between the intersection of a chord and a tangent.

To calculate for the angle between the intersection of a chord and a tangent we need to know the measure of the intercepted arc, and then divide it by 2 to get the angle.

If the measure of the arc CAB is given to be equal to 278°, then the measure of intercepted arc BC is calculated as:

arc BC = 360 - 278

arc BC = 82°

angle CBE = 82°/2

m∠CBE = 41°

Therefore, the angle m∠CBE between the intersection of the chord and tangent line is equal to 41°

Terry needs to carry a pole that
is 10 feet tall through a
rectangular doorway that
measures 6 feet by q feet. Will
the pole fit diagonally through the

doorway? Explain.
6 ft
9 ft

Answers

Answer:

Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole.

Step-by-step explanation:

Using the Pythagorean Theorem, ([tex]a^2+b^2=c^2[/tex] ) we can measure the hypotenuse of a right triangle. Since the doorway is a rectangle, and a rectangle cut diagonally is a right triangle, we can use Pythagorean Theorem to measure the diagonal width of the doorway.

Plug in the values of the length and width of the door for a and b. The c value will represent the diagonal width of the doorway:

[tex]6^2+9^2=c^2[/tex]

[tex]36+81=c^2[/tex]

[tex]117=c^2[/tex]

Since 117 is equal to the value of c multiplied by c, we must find the square root of 117 to find the value of c.

[tex]\sqrt{117} =10.8[/tex]

[tex]10.8=c[/tex]

Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole, measuring 10 feet.

Bob can type 2 letters in 4 hours while bill can do it in six. How many hours will it take them, working together, to type six letters

Answers

Answer:

7hr 12 min

Step-by-step explanation:

Given that

Bob can type 2 letters in 4 hours

while on the other hand bill can do it in six hours

We need to find out the no of hours in which they type 6 hours

So,

Bob's rate is

= 2 ÷ 4

= 1 ÷ 2 letter per hour

And,

Bill's rate is

= 2 ÷ 6

= 1 ÷ 3 letter per hour

Now

Together rate is

= 1 ÷ 2 + 1 ÷ 3 = 5 ÷ 6 letter per hour

We know that

rate × hours = production

Let us assume the hours be x

So,

(5 ÷ 6)x = 6

x = (6 ÷ 5) × 6

x = 36 ÷ 5

= 7 1 ÷ 5

= 7hr 12 min

The value of x in the figure which illustrates similar triangles is 3

How to determine the value of x?

The figure illustrates similar triangles.

This is represented by the following equivalent ratios

x : 6 = 4 : 8

Express as fraction

x/6 = 4/8

Multiply both sides by 6

x = 6 * 4/8

Evaluate the product

x = 3

Hence, the value of x in the figure is 3
